PORTABLE GUN.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed July 23, 1908. Serial No. 445,053.

To all whom it may concern:

g, Be it known that I, O'r'ro LAUBER, a subj ect of the Emperor ofGermany, and a resi dent of Essen-on-the-Ruhr, Germany, have inventedcertain new and useful Improvements in Portable Guns, of which the following is a specification. I

The present invention relates to portable guns, and the object of theinvention is to improve this type of guns in such a manner that the gunhas suflicient' stability on firing, even in case considerable lateraladjustment is im arted to the gun-barrel.

The object or the invention is attained by providing auxiliaryspade-members or stays provided with spades, the spade-members or staysbeing ointed to the mount in such a manner that they can be swung outlaterally to resist reaction of firing when the gunbarrel has beenadjusted laterally to a considerable extent.

One embodiment of the invention is shown in the accompanying drawings,by way of example. T I

Figure 1 is a side view of those-parts of a gun to which the inventionrelates, some parts being broken away, and Fig. 2 is the correspondingto View.

The gun barre B is mounted to slide on the slide-track carrier A which,through the medium of the horizontal trunnions a is swingingly mountedin the cradle O. Through the medium of an elevating mechanism the cradleC is connected with the slide-track carrier A and, through the medium ofa horizontal training mechanism, the cradle can be swung relatively to.the mount F about the axis oi' the vertical trunnion c journaled in themount F. The elevating mechanism and the horizontal training' mechanism,which are not shown in the drawings, may be of any suitable construction. However, attention is drawn to the fact that the lateral trainingmechanism and the connection between the cradleand the mount permit ofconsiderable lateral swing- The mount is provided with wheels Q and hasa trail provided with a spade f Two stays 0, each of which is providedwith a spade 0 are jointed to the side-walls of the mountnear thebearing for'the trunnion 0 By means of links P, which have one endjointed to the side-walls of the mount and have their other end jointedto slides 0 on the stays, the stays O can be swung about vertical boltsN which are mounted in bearings f on the walls of the mount. In theposition of travel the stays O almost lie against the side-walls of themountF as shown in dotted lines in Fig. 2. In the firing position thestays assume the position. shown in full lines in Fig. 2. Through themedium of bolts 0 the slides 0 can be rigidly secured to the stays inthe positions which correspond to the extreme inner and outer positionsof the stays O.- V

A view of Big. 2 will demonstrate that, when considerable lateralswingin -move ment is imparted to the gun barrelz one of the stays Owill always absorb the shock on firing. In this manner a tilting of thegun is in any case prevented with absolute certainty.

Without departing from the principle of the invention the trail propermight be com posed of two parts jointed together in such a manner thatthe two parts could be spread apart or folded together in a mannersimilar to the stays O.

Having thus described the invention, what is claimed and desired to besecured by Letters Patent is:

1. In a portable gun, thecombination with the mount and the gun ivotallymounted thereon; of a spade mem lerjointed to the mount and capable ofbeing swung laterally to the mount to a position opposite to thedirection in which the gun may be pointed.

2. In a portable gun, the combination with the mount, of a pair of spademembers jointed to the mount and capable of being spread apart in therear of the mount to resist forces at angles to the mount.

3. In aportable gun, the combination with the mount and its trailprovided with a gn gunt rearwardly and laterally.

spade, of an auxiliary spade member ointed The foregoing specificationsigned at Dusto the mount and capable and adapted to i seldorf, Germany,this 22nd day of June, support said mount rearwardly and laterally.1.908.

4:. In a portable gun, the combination with OTTO LAUBER. the mount, of apair of spade members jointed to the mount and adapted to support saidIn presence of- PETER LIEBER, WHLHELM FLAsoI-IE.
